no not really , you get to go skinny dipping but not really snorkeling there is a place on the beach you can do .. you get a little 2 person jet boat thing drive it to the reef then snorkel and drive back pretty cheap when we did it
I'm sure we snorkelled off the Boobs Cruise at least once but it wasn't impressive, having done same in the Red sea. Stick to snorkelling on deck with Chino !!
